Specification of Letters Patent.

Patented Apr. 1?, 1811?.

Application filed January 25, 1917. Serial Ito. 144,520.

To all whom it may concern:

Be it known that I, SAMUEL F. .PERKINB, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented new and useful Improvements in Kites, of which thefollowing is a specification.

This invention relates to improvements in kites and has for its objectto provide an inexpensive, powerful kite provided with suitablebalancing and steadying means, permitting the use of the kite for thepurpose of carrying men and loads of considerable weight.

The invention consists in the combination and arrangements of parts setforth in the following specification and particularly pointed out in theclaims.

Referring to the drawings:

F i bodylng my invention.

Fig. 2 is a plan view of the same.

Fig. 3 is a side elevation of the same.

Fig. 4 is a section taken substantially along the cross stick of amodified form of kite.

Fig. 5 is a frontelevationpf a slightly modified form of kite.

Fig. 6 is a detail side view of the lower portion of a kite similar inform to thatillustrated in Figs. 1 to 3 inclusive but illustrating amodified form of fin.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, 1 and 2 represent a pair of parallel upright sticks. 3represents a third stick disposed substantially at right angles to thesticks 1 and 2 and approximately one-third distance from the upper endsof said parallel sticks, said several sticks being secured together attheir crossing points.

A sheet of suitable material, preferably cloth 1, is arranged over oneface of the frame formed by the sticks, 1, 2 and 3, said sheet beingattached to the opposite ends of said sticks and having an outlinecoinciding with a figure represented by a line circumscribing said frameand connecting the extremities of said sticks.

Extending forwardly from each of the sticks 1 and 2 is a plane 5 and 6respectively, substantially coextensive with said sticks. These planesare arranged to unite along a line 7 disposed equidistant from thesticks 1 and 2. A fourth stick 8 is se gure 1 is a front elevation ofakite emcured to the lanes 5 and 6 along the juncture line 7 0 saidplanes and reinforces or stifl'eus the edge made by said planes.

The stick 8 is substantially shorter than the sticks 1 and '2 and theplanes 5 and 6 gradually decrease in length from that of said sticks 1and 2 to that of the stick 8. By cutting away the planes 5 and 6, asstated, wind pockets may be formed at 9, 9 beneath the opposite ends ofboth of said planes which tend to steady the kite, when in the air, fromwind striking against the outer faces of the planes 5 and 6. I

The sheet 4 has an opening 10 formed therein at the back of the planes 5and 6 so. that portions of the air which is caught within the pockets 9may escape to relieve some of the pressure therein. The fourth stick 8forms a support for a bridle consisting of cords 11 and 12 attached toopposite ends respectively of said stick 8 and uniting at 13, at whichpoint the captive line 14 is attached.

The outer ends of the stick 3 may be reinforced or braced by means of acord 15 extending from said outer ends forwardly to the stick 8 to whichsaid cord may be se-. cured. This cord also assists in maintaining thestick 8 central with respect to the nearly parallel with the stick 3 butupon the opposite face of the frame to that of said stick 3. The stick16 is not quite as long as the stick 3 and its ends are slidablyattached to said stick 3 preferably by suitable binding strands 17, 17which permit a slight movement of said ends relatively to the stick 3.

The reinforcing stick 16 is furthermore securely bound atopposite sidesof each of the sticks l and 2 by suitable binding strands, 18, 18 whichare wound a number of times about the sticks 16 and 3 over separatingblocks 19 that are inserted at opposite sides ofthe sticks 1 and 2. Thestrands 18, after being wound tightly in place, may

be covered with a coating of some suitable A cord 20 is stretched fromopposite ends of the stick 3, Fig. 4, and maintains said stick in aslightly arched state thus presenting a convex surface to the wind.

In 5 I have shown a structure similar to that shown in Fig. 4; with theexception that the stick 21, which is attachedlto the planes 22 and 23corresponding to the planes 5 and 6 of Fig. 1, along the juncture lineof said planes, is of somewhat greater length than the stick 8 of Fig.1, but short enough to provide pockets 24, 24 at opposite ends of saidplanes 22 and 23.

The planes 22 and 23 are, in this form, provided with openings 25, 25which are provided to relieve the pressure of wind against said planesand assist in steadying the kite in the air. One or more openings as at26, may be provided in the sheet 27 in this form of kite at the rear ofthe planes 22 and 23 which also assists in relieving some of thepressure within the pocket formed by said planes.

The cutting away of the planes 5 and 6 at their lower ends removes aconsiderable section of material which might otherwise assist insteadying the kite against lateral movement. This, however, is intendedto be counteracted by the exposing of more of the interior surfaces ofsaid planes and in producing longer pockets at 9 than would otherwise bepossible.

To still further counteract the loss of 35 area in the planes 5 and 6,due to the cutting away of said planes, a fin 28 is inserted betweensaid planes and extends from the stick 8 to the sheet 4 to which it issecured preferably by stitching along a line midway between the sticks 1and 2, thus maintaining said fin perpendicular to the sheet 4. The lowerend of said fin may be cut away at an angle coinciding with the angle ofthe lower ends of the planes 5 and 6, as shown in Figs, 1 and 3, or, ifdesired, the stick 8 may be extended at its lower end, as shown in Fig.6, permitting the fin 28 to be extended a considerable distance beyondthe lower edges of said planes 5 and 6.

Having thus specifically described my invention what I claim and desireby Letters Patent to secure is:

l. A kite having, in combination, two parallel sticks, a third stickdisposed at right angles to said parallel sticks and forming a frame, asheet adapted to cover one face of said frame and secured to oppositeends of said sticks, a pair of planes extending forwardly from saidparallel sticks and uniting along a line substantially shorter than anddisposed parallel with said parallel sticks and equidistant from saidsticks, said planes gradually decreasing in length from that of saidparallel sticks to that of said uniting line, and means for reinforcingthe forward edges of said lanes.

2.
